5.1 General
The appliance must be subjected to maintenance at least once a year, more often if necessary. If
applicable, ask a qualified installer for maintenance advice. Maintenance may only be carried out by
qualified maintenance technicians. When carrying out maintenance, the appliance must have been
shut down for an extended period. Make sure that you comply with all safety rules.
5.2 Cleaning
All gas-fired appliances require periodical maintenance. This maintenance work must be performed
by qualified maintenance technicians.
– Before starting maintenance work, the gas and electrical supplies must be shut off. See also
paragraph 4.7
– Check all gaskets and replace if required.
– The gas transport section is located on the side of the appliance in the electrical compartment.
The gas transport section can be removed from the appliance as a single assembly. To do so, six
M6 nuts must be removed and the electrical wiring disconnected.
– Removal of the gas transport section provides access to the burner and the ignition/ionisation
electrode. It is recommended to replace the ignition/ionisation electrode yearly during regular
maintenance.
– Check the burner surface for irregularities. Never use a steel brush!
– Clean the gas mixer using a soft brush. Make sure that no dust gets into the burner and the gas
suction tube. Refit the gas transport section, reconnect the wiring and the gas and electrical
supplies. [27]
